If we knew we were not alone in the universe it would have a very, very deep impact on our worldview, on our understanding of our place in the universe.

Science can proceed only if the scientist adopts an essentially theological worldview. ..even the most atheistic scientist accepts as an act of faith the existence of a law-like order in nature that is at least in part comprehensible to us.

We know that within the solar system is very unlikely there will be anything more advanced than microbial life, but if we think outside the solar system and then, the distances are, of course, immense, then there could be Earth-like planets with more advanced form of life.

Cancer is not something confined to human beings. It's found in all multi cellular organisms where the adult cells proliferate, so it's widespread in the biosphere. It's a phenomenon that is deeply related to the history of life itself, so by studying cancer I think we can illuminate the history of life itself and vice versa.

I always look on the black side of life. That way, you won't be disappointed and I'm cheerful if it doesn't work out. I'm a cheerful pessimist.

The language of chemistry simply does not mesh with that of biology. Chemistry is about substances and how they react, whereas biology appeals to concepts such as information and organisation. Informational narratives permeate biology.

Things changed with the discovery of neutron stars and black holes - objects with gravitational fields so intense that dramatic space and time-warping effects occur.

If we're thinking about old civilizations, those that formed a long time ago and there were stars and planets around long before Earth even existed, then these are going to be towards the center of the galaxy. That is the place to look if you think there are ancient civilizations that have made beacons or some other way of attracting our attention.

The secret of life does not lie in its chemical basis . . . Life succeeds precisely because it evades chemical imperatives.

Ultimate questions will always lie beyond the scope of empirical science as it is.

Perhaps the best motivation for going to Mars is political. It is obvious that no single nation currently has either the will or the resources to do it alone, but a consortium of nations and space agencies could achieve it within 20 years.

If we do discover more than one type of life on Earth, we can be fairly certain that the universe is teeming with it, for it would be inconceivable that life started twice here but never on all the other earth-like planets.

Should we find a second form of life right here on our doorstep, we could be confident that life is a truly cosmic phenomenon. If so, there may well be sentient beings somewhere in the galaxy wondering, as do we, if they are not alone in the universe.

My feeling is that scientific method has the power to account for and interlink all phenomena in the universe, including its origin, using the laws of nature. But that still leaves the laws unexplained.

Many investigators feel uneasy stating in public that the origin of life is a mystery, even though behind closed doors they admit they are baffled.
Paul Davies
Image
An argument often given for why Earth couldn't host another form of life is that once the life we know became established, it would have eliminated any competition through natural selection. But if another form of life were confined to its own niche, there would be little direct competition with regular life.

Are we alone in the universe? This is a question which goes back to the dawn of history, but for most of human history it has been in the province of religion and philosophy. Fifty or something years ago, however, it became part of science.

The Goldilocks Enigma is the idea that everything in the universe is just right for life, like the porridge in the fairy tale.

The secret of our success on planet Earth is space. Lots of it. Our solar system is a tiny island of activity in an ocean of emptiness.

To a physicist life looks nothing short of a miracle. It's just amazing what living things can do.

Scientists have no agreed theory of the origin of life - plenty of scenarios, conjectures and just-so stories, but nothing with solid experimental support.
